2 2000 Series Integrated Ultrasonic Plastic Welders IW/ IW+ 1100, 2200 & 3300 Watts Branson s 2000 Series Integrated Welders are self-contained ultrasonic plastics assembly systems that combine a power supply module, process controls, and welding stand in a compact bench unit to conserve work space, ease setup, simplify operation, facilitate relocation, and make service convenient. The integrated welder is the ideal entry level system for new users of ultrasonic technology and those with lower production requirements. Available with power output of 1100, 2200 or 3300 watts, the integrated welder Models IW and IW+ feature digital controls for accurate and repeatable setups. In addition, the IW+ models enable distance welding in either collapse or absolute modes with limits. When using the welder, the assembly operation is characterized by simplicity, speed, and efficiency. Once the system is programmed for a particular workpiece, no further adjustments are required. Key Features Line / Load Regulation - corrects for variations due to power line fluctuations and varying load conditions through Branson s proprietary closed-loop amplitude control. Output amplitude is maintained with a variation of only + 2% with line voltage fluctuations of +10%, regardless of load. It ensures constant power in welding and provides greater weld consistency and reliability. Line Regulation Load Regulation Auto Seek with Memory High Amplitude Converter 2000 Series 20 khz converter - produces 20% higher output amplitude than its 900 Series predecessor for faster weld cycles; in addition, this converter is more rugged and has higher power capacity. Auto Seek - automatically measures stack frequency and stores it in memory. Three selectable Auto Seek choices are available: 1. On power up, setting memory for the initial weld. 2. Depressing test switch. 3. By once/minute timer to track heating, cooling, and other effects. Operating modes - IW models feature welding in time; ultrasonics and force are applied to parts for a precise, preset time, and parts are held under force for a precise hold time; adjustable afterburst delay and duration times may be set, if required. Display of time and afterburst parameters is digital. IW+ models give choice of time or distance modes (either absolute or collapse). In absolute, the weld

3 is terminated at a predetermined point in the stroke, measured from the top of the stroke. In collapse, the weld is terminated at a predetermined point in the stroke after the horn contacts the part and the trigger switch is activated. The position display is digital. With position modes, upper and lower limit ranges may be selected. Digital parameter entry with autoranging - when entering parameters gives precise settings for repeatable accuracy. The autoranged values enable fine resolution and setup accuracy. A linear optical encoder - (IW+ models only) measures weld distance. The resolution on the encoder is inch ( mm). Afterburst with variable delay and duration - is available to dislodge a part or material adhering to the horn face. Individual select keys - allow easy selection of parameters to be modified. Active choice is lighted. Sequence of operation - is displayed in the digital LED window during the welding cycle. Self-diagnostics and cycle monitoring - features and capabilities provide fast, accurate troubleshooting and minimize downtime. During initial powerup, the unit completes a self-check and identifies any fault conditions or parameter errors before indicating that the system is ready for operation. Visual and audible alarms, and external outputs - identify overload, machine faults and setup errors (e.g., emergency stop engaged). Fast-response LED storage meter - displays power loading in 5% increments, and provides storage of the peak power achieved during the weld cycle as well as better visibility; 100% of rated output of the power supply is delivered at full meter reading. Peak power reading - from the last welding cycle is available on the digital LED display by depressing the reset switch. Similarly, power in the tuning mode is digitally displayed when the test switch is depressed. LED readouts display parameter settings - during setup and operation for easy reference and monitoring. LEDs are large and easy to read in most light conditions. Lockout of front panel switches - is provided by and internal dip switch, preventing unauthorized parameter changes to the setup. Nonvolatile storage of cycle parameters - provides storage of last-used cycle parameters even if the system is shut off or a power interruption occurs Series Equipment Standard Features Autotune plus Memory (AT/M) - Provides fully-automatic tuning in a range of Hz centered around khz for 20 khz horns and stores horn frequency at the end of each weld cycle. System Protection Monitor (SPM) - Five levels of power supply protection are provided: 1) phasing, 2) over voltage, 3) over current, 4) over temperature, and 5) power. The benefits of this feature are to avoid equipment failures and to provide greater weld accuracy and repeatability. Automatic pretriggering - is available to provide pretriggering without a mechanical switch to wear, adjust, or fail. Dynamic Triggering - provides consistent weld quality by initiating (triggering) ultrasonic vibrations after a preset force, ranging from lbs. ( N), is applied to the part. As melting of the plastic occurs, dynamic follow-through ensures the smooth, efficient transmission of ultrasonic energy into the part by maintaining horn/part contact and force. The range of dynamic follow-through is from lbs. (67 N to 890 N). The Dynamic Trigger mechanism of the 2000 Series includes a 48 position control dial for greater accuracy and con-

4 trol, and a self-contained optical switch for accurate repeatability and long-term reliability. Rugged construction and durability - Rigidity and consistent, precise alignment of the horn and parts during welding is provided by linear ball bearing slides. The slide system incorporates a rail in linear motion guides with four sets of preloaded, permanently pre-lubricated bearings. This design ensures long-term reliability (less wear, less binding) and allows smooth linear motion and well-balanced stiffness against loads applied from any direction. (For applications involving severe side loading, check with Branson before operation.) Preload is built into the bearings and does not depend on actuator assembly. The 1100-Watt model has a 2.5 cylinder, and the 2200 and 3300-Watt model has a 3 cylinder. Ease of setup and changeover - The converter/booster/horn stack is easily installed and removed from the front of the carriage assembly without repositioning the actuator. The stack may be rotated a full 360 in the carriage for horn alignment with the workpiece. Versatility Series Integrated Welders are capable of welding, staking, inserting, swaging, spot welding, and degating thermoplastics and can also seal synthetic fabrics, films, and other thin thermoplastic materials. A 4 stroke (102 mm) accommodates parts with deep cavities. The welding head can be rotated on the column; height is adjusted by turning a handwheel on the side of the unit. The system is compatible with automated systems and most material handling devices. Adjustable 20 threads-per-inch locking mechanical stop - with an adjustment knob. When properly set, the stop prevents the horn from touching the fixture or nest when no workpiece is in place. Upper limit switch - causes the power supply to produce a ready signal when the carriage has fully retracted. The ready signal is used as a safety interlock switch on automated systems to prevent the movement of material handling equipment (indexing) when the horn is down or the welder is in error. An optical switch is used to provide reliable, wear-free operation. Stroke indicator - allows quick identification of the operating stroke length. Convenient Pneumatic Controls Flush-mounted 2 diameter pressure gauge - provides excellent visibility for ease of setup; calibration is in both USCS (English) and metric (SI) units. High-precision regulator - provides accuracy and repeatability. Included is a locking feature pull to set, push to lock that enables consistency of operation once the unit is set up. Calibrated flow control valve - for downspeed gives accuracy, consistency and repeatability machine to machine. A locking mechanism is built in. Horn down key - on front panel facilitates setup allowing alignment of the horn with parts during setup without activating ultrasonics. Base with ergonomic low-force palm button - built-in emergency stop button. Mounting holes provided for attaching welder to work bench. Bolt holes for fixture mounting have M10 x1.5 metric threads. An optional self-leveling fixture plate for use with Branson Ergo base speeds setup and simplifies changeover of tooling. For automation or close mounting of welders, an optional mounting hub is available. Molded thermoplastic structural foam housing (Noryl ) - all internal electronic components are enclosed in a housing that is durable, compact, lightweight, non-conducting, and non-corrosive; single door access is provided to most internal components. product 2000IW/IW+ name

5 Automation Interfacing Branson s 2000 Series Integrated Welders can be interfaced with external devices and controls (e.g., PLCs). This will require both a J971 alarm cable and a J911 start cable (optional). A user I/O is built in. Select faults or weld errors sensed by the system can be communicated - outside the welder for monitoring and sorting suspect parts. Front panel or external reset access is provided. General alarm and weld on outputs - are available for customer access through 24V DC negative logic devices. The ready signal is both a 24V DC and isolated contact closure. External reset - is available for customer access as a 24V DC input. A w source is provided by the welder.
